旋流油水分離器含油污廢水沿著切線方向進入旋流管內，利用旋流時離心力不同，而達到分離效果。一般旋流油水之分離效果受到流量與滯留時間之限制。動態式旋流油水分離器採用由馬達帶動之旋轉筒，可在低流量下，達到高渦流速度，而得更佳分離效果。本子計畫將針對動態旋流分離器進行研究。將設計與製作一動態旋流分離器，以流場觀測方式進行實驗，以研究最佳之操作參數。並且以實際漁船油污廢水樣本進行處理，量測檢驗處離前後油水濃度以進行評估檢討。海洋法及水污法規定任何船舶不得於港口內及沿岸排放任何含油污水，以保護海域、河川及港口的生態環境。若採用光電觸媒污水處理系統與整合型廢油水與污水處理系統搭配使用，藉由TiO2被覆ITO上及高壓UV光的作用，將可有效防止電子(e-)與電洞(h+)的再結合(recombination)，可大幅提昇有機物降解效率。因此，本研究擬將廚房油污水以油脂截留器做為前處理，再導入傳統的油水分離器與機艙廢油水合併處理後，由光電觸媒污水處理系統作最終的淨化處理。而光電觸媒污水處理系統主要是濺鍍光觸媒鍍膜(TiO2/ITO)或光電觸媒鍍膜(Ag-TiO2/ITO)。 Oily waste water enters a hydro-cyclone in tangential direction and produces swirling motion to achieve separation effects. The performance of common hydro-cyclone is limited by the flow rate and residence time. Dynamic hydro-cyclone uses a motor-driven rotating barrel. High swirling speed may be achieved under low flow rates to obtain high separating performance. Based on the principles of dynamic hydro-cyclone, a hydro-cyclone oily water separator will be designed and practically built in this study. Experiments will be performed to observe the flow fields and study the optimum operation parameters. Oily waste water will be collected from fishing boats and handled by this hydro-cyclone oily water separator. The results will be examined and evaluated. This proposal is expected to build a photoelectrocatalytic reactor to treat oily wastewater to comply with 15 ppm oil/grease contented discharge regulated by MARPOL 78/82/97. In this study, we proposed a neat approach to deal with oily and grease-content wastewater in fishery boats. In the primary study, a set of sputtered TiO2/ITO film or Ag-TiO2/ITO film was photocatalyzed by a set of high-pressure UV lights. A bias potential will applied to this photoelectrocatalytic reactor in order to compare the organic reduction rate by these two approaches. It is expected to obtain a reduction rate of at least 90% in a 60 minutes reaction. Further experiment will be performed to shown that the proposed system still worked properly with the wastewater contained oil and grease in fishery boat.
